\section*{The Exercises}

We believe that our paper prototype exercises went fairly according to
plan.  Our customers seemed to generally navigate our exercises with
ease and their overall comments were quite favorable.  They thought we
had an attractive, easy-to-use interface for both our local client web
UI and our courier Android app. There were a few snags along the way
that we should have foreseen, though.

Our biggest problems were the small details.  For instance,
our paper UI had a temperature-selection widget that was drawn as a
series of check-boxes when the options were clearly mutually exclusive
and should have been radio selections fields.  Also, we naively forgot
about the ending scenario for our web UI cases: logging out.  We had
no logout method whatsoever and that was obviously a problem for our
customers.

We then had some issues that were a bit more surprising.  Our
customers had problems understanding our statistical diagrams on our
web UI view of incoming specimen for the lab (See figure
\ref{fig:labView}).  We thought it was rather obvious that it was an
ETA graph of the incoming specimen so that the lab could easily see
load patterns in the near future.  However, the low fidelity of our
graph labels coupled with the redundancy of having two graphs confused
everybody enough to merit some serious rethinking about their design
and a more usable integrated help system for the web client.

Again, we had the same surprised feeling when we were questioned on
the functionality on the lab view page.  It was misunderstood on what
parameters the search bar worked.  We have since decided to split up
its functionality into sortable columns for the table and a small
(well specified) search function for tags such as whether a specimen
is frozen, refrigerated, or time-critical.

We plan on making the customer changes noted above, along with some
other changes we have since thought about.  For instance, we will
certainly enhance our failure-saving functions so that things like a
hospital entering incorrect information for a specimen doesn't mean
calling up the lab to inform them of the mistake; it'll simply mean
going back from a ``review screen'' before committing the information,
clicking an ``edit'' button for that specimen before it's picked up,
or possibly, both.

Also, we believe a lot of the confusion during the exercises stemmed
from our preparations not being thorough enough.  The team was not
fully on the same page for the prototypes, and thus, it was hard for
our customer not to be confused some of the time.  We will remedy this
in future presentations by not entrusting the bulk of the presentation
material to a subset of our team without a full-team stamp, not
because it must be checked for quality, but because it ensures no one
is left in the dark on what is happening.

However, like stated before, our customer team said that they had an
overall favorable opinion of prototypes.  They thought the majority of
it looked clean and well thought-out.  That means we definitely don't
have to start from scratch, but we will definitely be tweaking things
down the road before actually implementing anything.
